Abstract

The present invention is directed to an unexpected benefit in a lithium cell which may be derived from using a combination of silver vanadium oxide prepared in a temperature range of about 450°C to about 500°C activated with a nonaqueous electrolyte having a passivation inhibitor additive selected from a nitrite, a nitrate, a carbonate, a dicarbonate, a phosphonate, a phosphate, a sulfate and hydrogen fluoride, and mixtures thereof. The benefits may include additional battery life resulting from a reduction in voltage delay and RDC build-up. A preferred electrolyte is 1M LiAsF6 in a 50:50 mixture, by volume, of PC and DME having dibenzyl carbonate added therein.
